Optical fiber attenuation distribution exists a certain amount of change

in the Cable production process

due to the impact of additional attenuation

optical fiber attenuation large area may cause Cable production attenuation exceeds the standard. In order to reduce the occurrence of such quality risks

the "attenuation non-uniformity" inspection item was introduced in the OTDR attenuation test. By observing the attenuation distribution of the whole section of the optical fiber

the abnormal areas that may cause excessive attenuation values were found and dealt with in advance. Therefore

how to improve the tester personnel with optical fiber attenuation non-uniformity resolution

is very important to reduce the quality risk.
